From Golf Magazine (July, 2010)
Callaway might be perceived as a "driver" company to the outside world, but since the late 1990s the firm has actually sold more irons each year than any other manufacturer. The ever-popular X-Series irons franchise (now in its seventh iteration) has a lot to do with the company's success. Its new X-24 Hot, billed as the longest, most-accurate X-Series iron, targets all players (regardless of handicap) who seek turbocharged distance in an iron.
Callaway engineers strengthened loft in the long and mid-irons (the PW is the same as in X-22 irons), increased shaft length by 0.25 inches per club (compared to the X-22), and redesigned the head to account for new weight distribution. The X-24 Hot also boasts evolutionary updates to tried-and-true design elements, such as "variable face thickness" (VFT) technology and "precision notch weighting" in the rear. VFT produces 2.2 mph faster ball speed than the X-22 irons do, for longer, more consistent length on mis-hits. The large cavity notch spreads weight to the heel and toe, for ample head stability and improved accuracy.

Callaway Golf has announced the release of the new X-24 Hot irons. The company is touting them as the longest and most accurate irons the company has ever made.
In a media release, Dr. Alan Hocknell, Callaway's senior vice president of research and development said, "We recognize there are golfers looking for distance gains throughout their entire bag, and thus employed our core technologies and faster ball speeds into the design of X-24 Hot, a longer, more accurate set than any of their predecessors."
Like previous X Series irons, Callaway designed the faces of the X-24 Hot to progress from thick on the bottom to thin along the topline. According to Callaway, this lowers the center of gravity and makes getting the ball into the air a lot easier. Read more ...
